Using the Same Pre Image in the Multi-Hop Locking Process of Lightning Network to Day

In the lightning network to day, we are using this idea of hash and pre image. And because it's the same pre image used across every hop in that route, that can potentially be used by a surveillance node. This is also enable something called a stuckless payment - where once you have sent a payment, if it gets stuck at some point in the route,. Right now, you don't have a choice but to wait for the payment to fail. If a node has appeared, instead of forwarding your payment, you could wait for a while. But with pitelses, we're able to change that. So that when when the payment is tuck, you can just kind of
